Step 6Preparing the Battery Holder

Preparing the Battery Holder
To protect the leads on the battery holder, slide a small piece of 1/16" heat shrink tubing into the holes through which the leads exit the holder. The battery holder barely fits into the tin and the heat shrink tubing protects the leads from abrasion. The orientation of the battery holder in the tin is chosen to keep the long lead on the component side of the tin.

Clamp the two wires together at the upper end of the holder with a short piece of 1/8" heat shrink tubing. Cut the end of the heat shrink tubing at an angle to get a closer fit to the holder.

Use diagonal cutters to cut the two tabs that hold the battery in. This will make replacing the battery considerably easier once everything is assembled
